Using Affine Jump Diffusion Models for Modelling and Pricing Electricity Derivatives
Abstract
A seasonal affine jump diffusion spike model with regime switching in the long‐run equilibrium level is applied to model spot and forward prices in the Scandinavian power market. The spike part of the model incorporates different coefficients of mean reversion in the spike and normal variables and thus improves the spot–forward relationship, particularly at time periods when spikes occur. The regime switching part of the model contains two separate regimes to distinguish between...
